Foldable Lamp with Shape-Sensing Brightness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps are inconvenient to move and store due to their large volume, and users find it difficult to intuitively adjust light brightness as the existing methods lack an intuitive interface for understanding light strength settings.
Innovation Solution
A lamp with a main body folded from a sheet, incorporating a sensing element that controls the light source based on the folded or unfolded state of the lampshade portion, allowing for intuitive operation and convenient storage by changing between a plane and three-dimensional structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the lamp is designed with a conventional fixed structure, then the lamp provides stable lighting function, but the lamp occupies large storage space and is inconvenient to move
Solution Approach 1:
The lamp is designed with a foldable structure that transitions from a fixed three-dimensional state during use to a compact folded state for storage and transport. The lampshade and lamp body can be folded relative to each other, reducing the overall volume while maintaining structural integrity and lighting functionality when deployed.
2Ease of operation
If the lamp provides multiple brightness levels via knob or section switch, then the lamp offers adjustable illumination, but the operation is not intuitive and requires additional adjustment of lampshade position and angle
Solution Approach 1:
The brightness control function is merged with the lampshade positioning mechanism. The sensing element detects the angular position of the lampshade relative to the lamp body and automatically adjusts the light source brightness accordingly. This integration eliminates the need for separate brightness control switches, making the operation more intuitive as users only need to adjust the lampshade angle to simultaneously control both light direction and brightness.
Solution Approach 2:
The lamp system performs automatic brightness adjustment based on lampshade position detection. The sensing element continuously monitors the lampshade angle and the control unit automatically modifies the light source output without requiring manual intervention from the user. This self-regulating mechanism simplifies operation while maintaining optimal lighting conditions.
3Loss of information
If the lamp uses conventional brightness adjustment methods with separate controls, then the lamp provides precise brightness control, but users fail to understand the relation between control settings and actual brightness levels
Solution Approach 1:
The system incorporates a sensing element that detects the physical position of the lampshade and provides feedback to the control unit. This feedback mechanism creates a direct, observable relationship between the user's physical adjustment (lampshade angle) and the resulting brightness level. Users can intuitively understand the brightness relation because the control input (lampshade position) directly correlates with the output (brightness) through a visible and tactile mechanism.

AI summary
This invention provides a lamp (1) including a main body (10), a light source, and a sensing element. The main body (10) is folded from a sheet, and the sheet includes a lamp holder portion (107), a lamp pole portion (101,105), and a lampshade portion (103). One end of the lamp pole portion is connected with the lamp holder portion. The lampshade portion (103) includes a plurality of creases (103a). The lampshade portion surrounds and is connected with the other end of the lamp pole portion, and the lampshade portion (103) changes between a folded state and an unfolded state along the creases (103a). The light source is contained in the lampshade portion. The sensing element senses a change between the folded state and the unfolded state of the lampshade portion (103) to control the light source.
